Let's start with the numbers. The Next America: Boomers, Millennials, and the Looming Generational Showdown is a recently-published book based on data collected by the Pew Research Center.

Obviously, sodium is an extremely reactive metal. When sodium comes into contact with water, it displaces hydrogen gas as follows: 2 Na(s) + 2H 2 O() 2 NaOH(aq) + H 2 (g). This is a dangerous reaction. If the sodium gets hot enough, the hydrogen jets can ignite and burn. That's what caused the sparks you saw. Burning hydrogen makes the temperature rise even faster.
